Boston Gear QC 700 Series NEMA Flanged Reducer Coupling Style
The Fastest Motor-Reducer Assembly in the West (and the East) Many maintenance engineers and industrial OEM’s choose couplings to connect their motors and gearboxes together. The advantages can be many, but the disadvantages can quickly add up.That’s because a slot must be cut in the gearbox flange to allow an Allen wrench to align the coupling… the same slot that lets in caustic washdown solution, water, and
Unique patentpending coupling design eliminates fretting corrosion and allows for blind assembly of NEMA motors.
other particles, also makes it challenging to see what you need when connecting the motor. That’s why Boston Gear developed the QC 700 Series, featuring a completely self-aligning coupling that eliminates the need for a slot in the flange and allows for quick motor and reducer assembly. Fretting corrosion is eliminated, which means your motor

QC 700 Series
• Super-finished oil seal diameters on both input and output shafts provide extended seal life.
• High pressure angle on worm provides greater operating efficiency.
• Integral input worm and shaft design made from high-strength case-hardened alloy steel. Reducer sizes 710 through 730 have pre-lubricant ball bearings: 732 through 760 have tapered roller bearings. Double lip oil seals are standard.
• Double bearing input design on all QC 700 sizes along with optional double seals.
• The elimination of the coupling alignment hole ensures that debris and bacteria will not collect on this reducer.
• This smooth, BISSC® approved clean motor flange dramatically improves any washdown application.
• Unique patent pending coupling design eliminates fretting corrosion and allows for blind assembly of NEMA motors.
• High strength steel output shaft assures capacity for high torque and overhung loads. • Large oil reservoir provides highly efficient heat dissipation and lubrication for longer operating life. • PosiVent® option is lubed-for-life, virtually maintenance-free.
• High-strength bronze worm gear is straddle mounted between heavy-duty tapered roller bearings to increase thrust and overhung load capacities, sizes 713-760.
• Rugged housing of fine-grained, gear-quality cast iron provides maximum strength and durability. Greater rigidity and one-piece construction ensure precise alignment of the worm and gear. This housing construction also provides superior resistance to caustic washdown solutions, plus high heat dissipation and reduced noise level. Pipe plugs allow easy fill, level and drain in any mounting position.
